Cartier - Gold and diamonds Trinity ring

Aglini - Cotton tie-neck shirt Fall/Winter 2010/11

Paul Smith - Wool turtleneck sweater Fall/Winter 2010/11

Two months ago, the British pop star, who recently launched a
17-piece collection in cooperation with the Fred Perry brand, was
seen in this good girl outfit in London.

Here are a few suggestions to reproduce her look: Aglini's checked
blouse with bow at the neck or Jeckerson's ruffled
number are perfect. Another alternative is Prada's
light blue menswear shirt with button-down collar.

On top, try a dark pullover like the one by Petit Bateau.
Another option is an indigo blue turtleneck by Paul Smith.
Depending on the occasion, you can wear destroyed denims by
Guess Jeans or J Brand's skin-tight faded
style.
